Technology under development
New Scientist has reported that the new generation electric cars have way more capacity in their batteries than they typically use. A standard urban range of an electric car is around 20-30 miles, yet the battery has the potential to store a 100 mile charge. Several research groups in the US and Australia are now pushing the idea that while sitting in your garage overnight, your electric car could store energy from renewable sources when supply exceeds demand. This could then be released back to the grid when needed. Essentially using your electric car battery as, well, a battery and a way to maybe make some money! That is an interesting idea nonetheless.
